Additionally to my previous above post; generally Waffen SS did not go to Einaatzgruppen volunterally. They went as a penalty for discipline or other offenses. Or some men in order to escape the hard fight of the Waffen SS units could askk for transfer just because it it is easier to kill unarmed jewas than to fight determined Russians. Another fact maybe not known widely is that the joining in Waffen SS was volunterally till 1943. After 1943 and 1944 while the Germans retreated everywhere, and it was very difficult to recruit men in order to replace the casualties, many men belonged to 'Volksdeutches' were obligatory joined Waffen SS. They knew that they have not in fact place in the future, Hitler was planned, because of their origin, so not easy you can call them Nazis. The ones who were put in first class Waffen SS divisions were absorbent easily and became same like the other fighters. However the second class divisions have not same level fight ability and they easily were fallen to atrocities. As a conclusion in Einaatzgruppen were not so many German Waffen SS. The Germans in Einaatzgrupen were members of police units or members of military police of Waffen SS. There were also other Waffen SS members but they were not Germans.
